I can't believe that it is true, but I heard that she wants to be there again for Koninginnedag (April 30th).

I was reading somewhere that she will not attend Koninginnedag!

About the Due-date. I don't belive in it at all.
I mean: the end of April?
It's March now and she already looks like she can give birth in every second.
... both , Amalia and Alexia, were born before the expected birth-date.

That will have been the freedom of the person who once started this thread.

By Royal Decree of 25 January 2002, nr. 41, Ms. Máxima Zorreguieta Cerruti is created Prinses der Nederlanden with the predicate Koninklijke Hoogheid. There are two reasons why Máxima is officially not known as De Prinses van Oranje:- since the title was made 'gender-neutral', the official opinion is that only the Heir(ess) Apparent is exclusively known as De Prins (Prinses) van Oranje- the title De Prinses van Oranje is a title en titre courteoisie. Princess Máxima however is created a Princess in her own right. Her own rightful Dutch title Prinses der Nederlanden outranks the courtesy Dutch title Prinses van Oranje.

__________________Today the world has embraced new royal Princesses in the form of Mary of Denmark and Maxima of the Netherlands. But it's questionable whether even these hugely popular, increasingly glamorous future Queens will ever capture the world's imagination in the same way as Diana.As Mario acknowledges: "She really was a true Princess".-www.theroyalist.net-

Henri, if Maxima is on paternity leave & wanted to attened a certain function/event along with the queen (one of the events she usually goes to with the queen) could she attened ?

The Princess has no 'maternity leave' in the correct meaning of the word. After all she is not employed or something. She is just her own boss and she has the freedom to determine her own agenda and schedule, in cooperation with the other core members of the royal family.

Every monday morning at Huis ten Bosch there is a so-called 'secretarie', a meeting with the Queen, the Prince of Orange, Princess Máxima and main figures of the Household (the Grandmaster, the Treasurer, the Master of the Ceremonies, the Grandmastress, the Stablemaster, the Chief of the Military House, etc.) So now and then Princess Margriet and/or Prince Constantijn do attend this 'board meeting' as well.

The Princess can simply say that she will not take up engagements then and then, if she pleases so.
